One thing I might add is that you should decide if you are working in the shop primarily alone, or will you have others working there at the same time. In most cases in a hobby shop its just one person, so you most likely would have only yourself, and on rare occasions, two people working at one time and because of this you dont have to go whole hog and put in tons of power.

Any outlet should always be 20 amp. 15 amp circuits are primarily for lighting, so plan to use at least 20 amp circuits. I can use my bandsaw and have the dust collector and air filter all running off 20 amp circuits and it runs fine off the 60 amp breaker box. The table saw is on 220 V and it’s on the same box.

If you are not familiar with electric work, like many have said, its best to have someone wire it for you. You should be fine though in a hobby shop with about a 60 amp box with plenty of 20 amp circuits (about 4 to a breaker) and a couple of 220s at 30 amps if you need them for large equipment like the table saw or stationary planer etc.
